We're dividing 448643 by 25 
Our goal is to divide 448643 by 25.

Step 1:
4 divided by 25 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 25

On to step 2:
25 goes into 44 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 25 away from 44, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 25

Step 3:
When dividing 198 by 25, we get 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 175 from 198 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 25

Advancing to step 4:
When dividing 236 by 25, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtract 225 from 236 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 25

Going ahead to step 5:
25 can be fit into 114 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 1794.0
If we subtract 100 from 114, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 25

Let's proceed to step 6:
143 divided by 25 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 17945.0
If we subtract 125 from 143, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
180 divided by 25 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 17945.7
Deduct 175 from 180 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 17945.72
Deduct 50 from 50 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17945.72
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17945.72
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 17945.72 with a balance of 0.0.
